Espruino MQTT Hub - Repeater Mode? Extend BT Range?

FYI - to determine if both the system and my Mom are OK, I look at things like

1. Temperature of the puck (higher when she is wearing it as opposed to lying on the counter top)
   
2. Motion, obviously
   
3. RSSI changes as she is in one room versus the other
   
4. Presence, obviously
